iPhone 17 Pro system storage issues after deleting cloud and local data

New iPhone pro 17 on iOS27.0.1 system storage issues after deleting massive GB cloud and local system storage?


Is there a setting to block the iPhone storage in your phone from reassigning random iCloud data that clogs up your phone usage after clearing space?


Or a way to preserve the recently cleared iPhone storage?


Currently deleting data on phone also deletes from iCloud as well, which defeats purpose of cloud data.


I have deleted GB of iPhone messages, apps, & photos to free up space as well as deleting my search engine cache and still my iPhone system storage refills. I’ve taken screenshots over the course of days of deleting data and as soon as I clear GB, the next day I have the same storage full message. I deleted my instagram app which was 72GB alone and the next day, “storage full.” I’ve deleted 100s of GB of message attachments and 1000s of messages & videos.



I am paying for iCloud storage, I don’t want to export to Dropbox or hard drive to save messages and photos in order to delete from my phone which currently also deletes from my iCloud.


*Also my storage capacity is 256GB and iCloud is 6TB. iCloud is not full, but local phone storage is.

The purpose of iCloud is to synchronize with your phone and to make your stuff available on other connected devices. It's possible that iCloud is not what you really want.


It would be helpful to have actual data about your situation. What is your storage on this iPhone? At Settings>General>iPhone Storage, my phone says 50.5 GB of 128 GB used. What does yours say? 


If you don't get your storage below 90%, say 230 GB, then you will continue to have trouble. Many operations use the iPhone's empty storage space to move files around. If you run out of storage, then those operations may not be able to be completed and, ironically, that can mean that even deleting doesn't work. If you have less than 10% available, then things can get lost forever.

You'll need to keep deleting/offloading data off your device to gain back more memory.
